The tumor is found in one or both ovaries and has spread into other areas of the pelvis. Stage II is divided into stages IIA, IIB, and IIC. In stage IIA, the tumor has spread to the uterus and/or fallopian tubes (the long slender tubes through which eggs pass from the ovaries to the uterus). In stage IIB, the tumor has spread to other tissue within the pelvis. In stage IIC, the tumor is found inside one or both ovaries and has spread to the uterus and/or fallopian tubes, or to other tissue within the pelvis. Also, one of the following is true: (1) tumor cells are found on the outside surface of one or both ovaries; or (2) the capsule (outer covering) of the ovary has ruptured (broken open); or (3) tumor cells are found in the fluid of the peritoneal cavity (the body cavity that contains most of the organs in the abdomen) or in washings of the peritoneum (tissue lining the peritoneal cavity).
